Setup
1. Mounting the Riflescope
Proper mounting is crucial for accuracy. Use appropriate scope rings and bases designed for your rifle and the 1-inch tube diameter of this riflescope.
- Secure the bases to your rifle according to the manufacturer's instructions.
- Place the lower halves of the scope rings onto the bases.
- Position the riflescope in the lower rings. Ensure the reticle is level and the scope is oriented correctly.
- Attach the upper halves of the scope rings, tightening the screws evenly to avoid stressing the scope tube. Do not overtighten.
- Adjust the eye relief by sliding the scope forward or backward until you achieve a full, clear field of view when shouldering the rifle naturally. The eye relief for this scope is approximately 3 inches.

2. Bore Sighting
Bore sighting is an initial alignment process that helps get your scope close to zero before live firing, saving ammunition.
- Use a bore sighter tool or visually bore sight by looking through the rifle's bore at a target and then adjusting the scope's reticle to the same point.
- Perform fine adjustments at a shooting range.
3. Eyebell Focus (Reticle Focus)
The eyebell focus adjusts the clarity of the reticle.
- Point the scope at a clear, bright area (like the sky) and quickly glance through it.
- Rotate the eyebell (the ring closest to your eye) until the reticle appears sharp and clear. Avoid staring through the scope for too long during this adjustment, as your eye may compensate for blurriness.
Operating Instructions
1. Magnification Adjustment
The magnification ring allows you to change the power of the scope from 6x to 24x.
- Rotate the magnification ring (located forward of the eyebell) to your desired power setting.
- Higher magnification provides a closer view but reduces the field of view and can amplify natural hand shake.

2. Parallax Adjustment
Parallax is the apparent movement of the reticle against the target when your eye moves off-center. This riflescope features an adjustable objective lens for parallax correction.
- Rotate the objective lens housing (the front-most part of the scope) to match the estimated distance to your target.
- The parallax setting ranges from 15 feet to infinity. Adjust until the target and reticle appear to be on the same plane and there is no apparent shift when moving your head slightly.

3. Windage and Elevation Adjustments
The windage (horizontal) and elevation (vertical) turrets are used to zero your riflescope. Each click of the turret adjusts the point of impact by 1/4 MOA (Minute of Angle).
- Remove the protective caps from the windage (side) and elevation (top) turrets.
- To move the point of impact UP, turn the elevation turret counter-clockwise.
- To move the point of impact DOWN, turn the elevation turret clockwise.
- To move the point of impact RIGHT, turn the windage turret counter-clockwise.
- To move the point of impact LEFT, turn the windage turret clockwise.
- After zeroing, replace the protective caps.

4. True Mil-Dot Reticle
The True Mil-Dot reticle provides reference points for range estimation and bullet drop compensation. Familiarize yourself with Mil-Dot calculations for effective use.
Maintenance
Cleaning the Lenses
Always use a soft lens brush or compressed air to remove dust and debris before wiping.
- Use a clean, soft lens cloth and a small amount of lens cleaning fluid.
- Wipe gently in a circular motion from the center outwards.
- Avoid using harsh chemicals or abrasive materials, as they can damage the lens coatings.
Cleaning the Body
Wipe the riflescope body with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by wiping with a clean, damp cloth.
Storage
Store the riflescope in a cool, dry place, away from direct sunlight and extreme temperatures. Use lens caps when not in use to protect the lenses.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blurry Image / Reticle | Improper eyebell focus or parallax setting. | Adjust the eyebell for reticle clarity. Adjust the objective lens for parallax correction to match target distance. |
| Scope Not Holding Zero | Loose mounting rings or bases; damaged scope. | Check and tighten all mounting screws. Ensure rings and bases are correctly installed. If the problem persists, contact customer support. |
| Limited Field of View | Incorrect eye relief; high magnification setting. | Adjust eye relief by moving the scope forward or backward. Reduce magnification for a wider field of view. |
| Adjustments Not Responding | Turret caps not removed; internal mechanism issue. | Ensure turret caps are removed. If turrets still do not click or adjust, contact customer support. |
